Tribotechnical Properties of Edible Vegetable Oils

Abstract

The basic mechanical and tribotechnical properties of olive, corn, sunflower, rapeseed oils and mineral oil I-20 were determined. It is found that mechanical properties of oils are comparable or better to properties of I-20, as well as their load-carrying capacity meet or exceed up to 60 %, antiwear properties are more effective of 1.3-2.3 times, load wear index is higher by 2.3 times. According to tribological characteristics, the oils are ranked from best to worst as follows: olive, corn, rapeseed and sunflower.
